6 SURFACE MACHINERY AND METHODS FOR OIL-WELL PUMPING.
QUALIFICATIONS OF THE OWNERS AND OPERATORS AS A FACTOR.
Companies that lack capital and good financial standing often
fail because of the lack of funds with which to improve operating
methods and equipment. This is as true in the production of oil as
in any other industry.
Among the most important of the operating factors are the au-
thority and ability of the manager. Lack of vested authority and
lack of executive ability on the part of the manager have wrecked
many prosperous companies. On the other hand, the manager may
be so capable that he can make operations pay even though handi-
capped by an incompetent group of directors and lack of capital.
The older and larger oil companies generally have strong organiza-
tions as a result of years of development, but many of the smaller
and newer companies operating in the gusher fields have suffered
greatly from lack of management and organization.
PRIME MOVERS AND POWER-PLANT MACHINERY.
Prime movers used to supply power for oil wells are classified as
to use, as follows: 1, Those at the well for individual drive; 2, those
at or near a group of wells for group drive; and, 3, those in the gen-
eral area to be served that can supply power to pump all of the wells
of a number of properties, either individually or in groups.
Type 3 refers to the common type of electric power plant. The
power generated is carried on high-tension lines to the distributing
station, often on the property to be served, where it is stepped down
through the transformers and is used either to drive the motor of a
central jack pumping plant or is carried on low-tension lines to the
motors of the wells pumped " on the beam."
Prime movers and power-plant machinery for pumping oil wells,
and for use as auxiliary power at pumping oil-well properties, are
classified as to type and discussed as follows: 1, Steam boilers, steam
plant equipment, and fuels; 2, steam engines; 3, gas engines; 4, oil
engines; 5, compressors; 6, pumps; 7, electric generating equipment;
and 8, horses used for bailing and pulling oil wells.
STEAM BOILERS, STEAM-PLANT EQUIPMENT, AND FUELS.
The capacity of a boiler is usually expressed in boiler-horsepower.
The standard at present is that recommended by the American
Society of Mechanical Engineers. The committee on boiler tests
of this society defines the boiler-horsepower as the equivalent evapo-
ration of 34.5 pounds of water from and at 212 F. an hour. This
is equivalent to 33,479 B. t. u. an hour.
